QED Silver Anniversary XT Unterminated Speaker Cable (Per Metre)

The QED Silver Anniversary XT sits within QED’s Classic range, positioned above the Performance XT25 and below the Reference XT400 and Golden Anniversary XT in the speaker cable hierarchy. It is the direct replacement for the original multi-award-winning Silver Anniversary cable, adding QED’s X-Tube technology to a proven silver-plated conductor design.

X-Tube Technology

The defining feature of the Silver Anniversary XT is QED’s X-Tube construction. At high frequencies, conventional cables suffer from the skin effect, where current concentrates near the conductor surface rather than flowing uniformly across the full cross-section. X-Tube addresses this with a polycore geometry that maintains near-linear signal transfer at elevated frequencies, preserving detail and timing accuracy that standard cable geometries compromise.

Conductor & Insulation

The cable uses silver-plated 99.999% oxygen-free copper conductors in a unique SPOFC triple braid configuration of 5 × 16 × 0.1 mm strands. The silver plating improves high-frequency conductivity, while the high-purity OFC base ensures low resistance across the audio band. A high-performance low-density polyethylene dielectric minimises signal energy loss from cable capacitance, reducing dielectric absorption and signal smearing.

Practical Considerations

Silver Anniversary XT is sold unterminated by the metre, allowing custom cable runs to be cut to the exact length required for any installation. The compact 3.90 mm jacket outer diameter makes routing straightforward, and the cable is suitable for all installation types. QED offers a lifetime guarantee on the cable.
